This fits in with the concept of the so-called Internet of Things (IoT). to supervise environmental parameters prevailing in a group of cold stores, warehouses or production halls. Gathered informations can be used for processing and visualization – e.g. It is possible to create a server that will collect data from many modules. The module can send measurement data using the MQTT, JSON, JSON/HTTP and MODBUS RTU open communication protocols, via GPRS. Additionally, GPRS-A has a 1-Wire bus, to which up to 8 DS-T1 digital temperature sensors can be connected. Those that work as analogue ones can be used in automation systems or to monitor a wide range of external devices, such as temperature, pressure and humidity sensors. The device has 8 inputs, which can be set as digital (NO, NC) or analog. It connects to the control panel with the control panel dialer or appropriately configured outputs. In the alarm systems, this module can be used to implement reporting, in conjunction with any alarm control panel. The device is provided with a GSM telephone that supports data transmission in GPRS technology. GPRS-A is a universal monitoring module that can work as a stand-alone device or as part of intruder alarm systems as well as automation systems.
